1.	What is the solution of (y(dy/dx) + 2x)² = (y² + 2x²)[1 + (dy/dx)²]?
A.	cx<sup> 1/ 2</sup> = y/x + (y<sup>2</sup> 2x<sup>2</sup>)/x<sup>2</sup>
B.	cx<sup> 2</sup> = y/x + (y<sup>2</sup> + 2x<sup>2</sup>)/x<sup>2</sup>
C.	cx<sup> 1/2 2</sup> = y/x + (y<sup>2</sup> 2x<sup>2</sup>)/x<sup>2</sup>
D.	cx<sup> 1/ 2</sup> = y/x + (y<sup>2</sup> + 2x<sup>2</sup>)/x<sup>2</sup>
Answer» E.
